' In Switzerland July 2, 1935 2 Claims. (Cl. 15-458) My invention relates to suction nozzles for use changes the position of valve chamber l8 by virin connection with a vacuum cleaner and partue of the fact that the valve chamber is unticularly to duplex nozzles provided with openbalanced about its pivot. The part 20 of the ings of different sizes which may be selectively valve member to the left of the pivot, as seen in connected to the source of suction. When the Fig. 2, is heavier than the part on the other side 5 larger opening is in use it will-cover a larger of the pivot, whereby the part 20 will always be surface, thereby increasing the speed of cleaning. in the lowest position possible. Consequently, However, if a concentrated suction is desired in when the nozzle II is turned over to bring the reorder to remove dirt which the larger opening stricted opening I3 in contact with the fioor, the
